The warm and muggy feeling can be attributed to high relative humidity that limits the amount of sweat evaporated from our skin. If there's a difference between the dew point temperature and the air temperature, then things shift. Stefan Boltzmann law calculator uses the temperature and emissivity of a body to find the power radiated from it. For example, a temperature of 30 and a dew point of 30 will give you a relative humidity of 100%, but a temperature of 80 and a dew point of 60 produces a relative humidity of 50%. In this case, the indoor air could become very dry if you do not run a humidifier.

This is the Temperature And Humidity Relationship Chart: This chart tells us everything we need to know about how humidity affects our perception of temperature. Dew point is the temperature of the air when it cools to a point where it saturates with water vapor (known as the dew point temperature). IMPORTANT: Heat index values were devised for shady, light wind conditions. (1000-3000+ Sq Ft Homes), Thermostat Says Heat On But No Heat? Once the funk wants to get air-borne it is ripe for vacuuming or dry-scathing alone (no chemicals) and you will remove a large majority, maybe 98% of the growth that had a potential to get air-borne.

Your initial analysis may say something like 7,000 mold spores per cubic meter of air for a humid vented crawlspace during the middle of the summer, with visible mold and then you may seal it all up, install a dehumidification system, or do waterproofing and 8 weeks of dryness later after your mold sampler has crawled through the now dusty crawlspace knocking everything down and picking everything up to start your follow up test after the work done, you may have solved the humidity problem, made the space much more inviting and clean, but get an analysis back that there are 77,000 mold spores to the cubic meter. This Temp/RH information is critical for understanding the actual moisture situations we face.
